GAS-STOVE.

Specification of Letters latent.

Patented Sept. 2, 1913- Appl'ication filed March 23, 1912. Serial No. 685,778.

i for increasing the heating efiiciency thereof.

- trated in Fig.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in whiclb' V Figure is a perspective view of a gas stove equipped with means embodying-my invention, Fig. 2, an enlarged section through the top of the stove above a burner, Fig. 3, a perspective view of a housing employed in the 1 construction, Fig. A, a perspective view of a modified form of housing shown in inverted position, Fig. 5 is a vertical section taken upon the line 55 of Fig. 4, and Fig. 6 is a detail perspective view of one of the burners'illus- 1, parts being broken aw ay.

The form of construction illustrated.in Figs. 1, 2 and 3 of the drawing comprises a downwardly tapering sheet metal housing 1 adapted to fit over and rest upon a burner 2 of the stove Housing 1 is provided at its upper edge with notches 3 adapted to receive the usual supporting fingers 4 of the stove and at its lower edge with notches 5 adapted to admit air to facilitate combustion, By this arrangement v the heat and flame from a burner will be confined and concentrated against the bottom of the cooking utensil, and thus the heating efliclcncy thereof increased.

In the form of construction shown in Fig. 4 a cylindrical housing 6 is provided having notches 7 in its upper edgcadapted to receive the supporting fingers. 4 of the and a have invented.

stove, and notches 8 in its lower edge adapted to admit air as before. A sup porting flange 9 is secured to the lower edge of housing 6 by means of tongues 10 thereon which are passed through slots in said flange and bent over against the bottom of the flange as shown in Fig. 2. In

, this construction the flange 9 is designed to rest upon the burner and the notches 7 to receive the supporting fingers as before. By extending flange 9 both inwardly and outwardly, a broad supporting surface is presented and a secure fastening afforded for tongues 10. The action of this form of housing is the same as being provided to fit adiifcrent style of burner.

While I have illustrated and described the preferred forms of construction for carrymg v invention into effect, these are capable of variation and modification without departing from the spirit of the invention,

1, therefore, do not wish to be limited to the precise details of construction set forth. but desireto avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new;;;and desire to secure by Let: ters Patent is:v

1. The combination with a gas stove burner, of a housin burner and arrange to confine the-flame against the bottom of a cooking utensil. said housing being provided with notches at its upper edge adapted to receive the utensil before, this form positioned ovcr the supportingfingers of the stove, said notches,

being'largcr' than said fingers to afford ven' tilation; and with notches at its lower edge adapted to admit air, substantially as describedr 2. The. combination with a gasstove burner, of a cylindrical housing positioned over the burner and arranged to confine the flame againstthe bottom of a cooking utensil. said housing being provided with notches at its upper edge adapted to receive the utensil supporting fingers of. the stove and with notches at its lower edge In testimony whereof I have signed my name to this specificatipn in the presence of two subscribing witnesses.
